B22-M3 and Boot from SAN with W2008 R2 SP1

[Walter Dey]

I have a rather weired situation.

Service profile with boot from SAN

Associate with a B22-M3

Boot lun visible

Installing W2008 R2 SP1 on a boot lun (HDS storage) works perfekt

However, boot fails ! we see Windows starting, and then it starts loop, booting again and again

Associating this same Service Profile to a B200-M3 works, Boot from SAN is ok

Has this been seen ?

[Robert Burns]

Walter,

Which adapters are you using in the B22 and B200?

Robert

[Walter Dey]

Hi Robert

B22-M3 has a MLOM, B200-M3 has MLOM and VIC-1280

I have seen some issue, which could explain the issue: the memory Dimm's in the B22-M3 are not properly configured ! I have to investigate further and let you know.

Btw. I forgot to mention, that for the B22-M3, Windows actually blue screens, upon booting from the lun.

Cheers

Walter.

[Robert Burns]

Yeah that BSOD could be a problem.  I'd also remove the VIC 1280 from the B200 to ensure the VIFs aren't being instantiated on it.  Compare Apples:Apples this way.

Looking forward to your update once the memory issue is sorted.

Hi Wdey,

Is the firmware on both the B22 and the B200 server the same? If not lets make sure that the servers are running the correct firmware.

Thank you

[Walter Dey]

Hi Manuel

UCS domain run's at 2.1.3a

Firmware on both blades are at 2.1.3a as well

Is this correct ?

[Keny Perez]

That does not seem right...

If he wants 32 GB of memory, he needs to configured it like:

B0  B1   C0   C1   D0   D1

4     4      4     4      8       8     <<<< DIMMs size

What he can do is to move the 16GB DIMMs and move them to D0-D1 and buy 4x 4GB to install them in B0-1/ & C0-1 to have 48GB DIMMs and take advantage of the DIMMs he already has

-Kenny

[Walter Dey]

Thanks Keny ! This configuration is also running at 1600 Mhz (if Dimms and CPU support 1600 Mhz) ?

I have yet another question, of a 2 CPU, 8 x 16G Dimm (128GB) B22-M3, where discovery fails ! could this also be a memory configuration misconfiguration ?

According to the installation guide for B22-M3

4

B0, C0, D0, B1

F0, G0, H0, F1

Above should be ok and run at 1600 Mhz ! please confirm ?

[Walter Dey]

Keny, now I'm really confused.

If you look at the installation guide of B22-M3, table 2, http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.pdf, it says B0, C0 !! which contradicts, whats in the B22-M3 Spec

Table 2: Preferred DIMM Population Order

DIMMs per CPU CPU 1 installed slots CPU 2 installed slots

1 B0 F0

2 B0, C0 F0, G0 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

3 B0, C0, D0 F0, G0, H0

4 B0, C0, D0, B1 F0, G0, H0, F1

5 B0, C0, D0, B1, C1 F0, G0, H0, F1, G1

6 B0, C0, D0, B1, C1, D1 F0, G0, H0, F1, G1, H1

[Keny Perez]

Walter,

I think the confusion here is the fact that both (the spec sheet and the installation guide) talk about either 1 DIMM per channel OR 2 DIMMs per channel.  Your customer is doing both at the same time  {EDIT: I am not saying that is wrong, I am saying that is the confusion you see when looking at both documents}

-Kenny

[Walter Dey]

Hi Kenny et al

Just to summarize the inital problem, again, and highlight the discrepancy in different Cisco documents.

Customer ordered B22-M3 with one CPU and 2 x 16 G Dimm.

He then opens the blade, and compares the shipped configuration, which I assume is done like in the B22-M3 spec

http://www.cisco.com/en/US/prod/collateral/ps10265/ps10280/b22m3_specsheet.pdf
Table 24 , namely D0, D1 (as Kenny said above)

customer then checks http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.html
Table 2, which says B0, C0

And changes B0, C0 to D0, D1, which might be wrong !!!!

Thanks for any clarification ! it's urgent

Thanks Walter.

[Keny Perez]

Walter,

How much memory did your customer wanted to have installed in the server (as a total and not per CPU) ?

-Kenny

[Walter Dey]

B22-M3 with one CPU and 32 GB; with 16Gb Dimm's
